postprocess script ' ' does not exist

Error message

postprocess script '%s' does not exist

What it means

_setPostprocessFunctions iterates over the comma-split values of --postprocess and, per script, first checks os.path.exists. This is an existence guard: when the path given on the command line does not exist on disk (typo, wrong relative path, deleted file), a SqlmapFilePathException is raised with the raw script value embedded in the message.

Solutions

1. Check the path passed to --postprocess for typos; use an absolute path if unsure.
2. Verify the script file actually exists at that location (`ls <path>`).
3. Watch for shell splitting: if the path contains spaces, quote it; note sqlmap splits multiple --postprocess scripts on commas.
4. Confirm file permissions allow the running user to read the script.
